편도 주위 농양의 세균학적 고찰 = Bacteriologic Evaluation of Peritonsillar Abscess

다국어 초록 (Multilingual Abstract)

Background and Objectives：Peritonsillar abscess (PTA) is a collection of pus lateral to tonsil and is located betwen the fibrous capsule of the palatine tonsil, usualy at its upper pole, and the superior to the pharyngeal constrictor muscle. It frequently occurs as a complication of acute tonsillitis. Bacteriology including clinical characteristics in PTA were evaluated. Subjects and Method：2001 were entered into the study. Each patient was asked to answer a questionnaire for clinical aspects of PTA. Needle aspirations were performed and pus was drained in all cases. Bacterial susceptibility to ampicillin, cephazoline, ciprofloxacin, erythromycin, tetracyclin, and vancomycin was tested on the ioslated bacteria. Results：Among 61 cases, aerobes were isolated in 15 cases (24.6%) and anaerobes in 16 cases (26.2%). There was no significant diference in the culture positive rate of aerobes (p= 0.767) and anaerobes (p= 1.0) betwen antibiotics-medicated patients and nonmedicated patients. Among the cultured organisms, peptostreptococus was the most comon and the second most comon was β-hemolytic streptococcus. However, α-hemo-lytic streptococcus, an important pathogen considered in the previous study, was detected at 1.6%. Conclusion：Antibiotics medication was not a significant factor in culture positive rate in our study. Peptostreptococus as an anaerobe and β-hemolytic positive rate of α-hemolytic streptoccus.
